Prefix every chunk with its document title and heading path

A chunk that says "rotate the key, then restart the workers" is ambiguous. "Payments runbook / Key rotation / rotate the key, then restart the workers" matches the query on the words that matter. Chunk on structure, not on a fixed token count, and carry the path.

Session cookies: HttpOnly, Secure, SameSite=Lax

securityhttp

Three attributes, each closing a class of attack. HttpOnly keeps scripts from reading it. Secure keeps it off plain HTTP. SameSite=Lax stops it being sent on cross-site POSTs, which is most CSRF.

Set-Cookie: session=...; HttpOnly; Secure; SameSite=Lax; Path=/; Max-Age=1209600

Strict breaks arriving from an external link while logged in. Lax is the default worth keeping.
